It runs against hardware virtualization... I'm not sure I understand why it needs a "real" OS underneath. At least in theory it should be able to run on bare metal as long as you include logic for whatever device drivers you might need.

Microkernel and RTOS work shows anything it needs can be about as tiny as itself. Tinier, actually, if it's a networked service with a single app running. It already has networking, needs a driver, a few special-purpose components... not much left to add.
